We should let more scientists apply the Bible.

This is a quote from an article on overpopulation (apparently there are now 7 billion people in the world).

I love the old biblical statement from Isiah [sic] - 'all flesh is grass'. That's actually a brilliant statement because it summarises the basic truth that we are only here on Earth because we can trap the energy in sunlight and turn it into something of use to us. And the best way of trapping the energy of sunlight, virtually the only way we've got, is to use chlorophyll - the green stuff in plants - to turn the solar energy into a plant which we can eat or harvest and do what we like with. So ultimately our future depends on the ability of the Earth to trap that solar energy, and for a plant to grow, it needs water.
